Mail Act-On is a plugin Apple’s Mail in that allows you to map specific mail rules or actions to “Act-On” keys. When viewing mail you can apply an “Act-On” action for a message by making simple keystrokes. Mail Act-On makes use of Mail’s existing rule engine, so if you have ever created a rules, you already know 99% of what you need to know to build an Act-On action. Imagine, no AppleScripts or other macros. (Even if you haven’t ever created a mail rule, there is very little to learn!)

Reduce the effort required to manage your email
Perform multiple actions on messages in a fraction of a second and eliminate time consuming and error prone manual organization such as drag and drop message filing.

Process multiple messages simultaneously
A single keystroke can apply multiple rules on your selected messages. Different actions will be taken depending on the characteristics of each message, letting you clear your inbox even faster.

Organize more than just your inbox
Outbox rules give you the power to apply organization actions to messages you send.. Apply Act-On rules to related messages to organize older messages, no matter where they are located.
